SPECIFICATION forming part of Letters Patent No. 813,12, dated March 3, 1885.

Application filed August 8, 1883.

To aZZ whom it may concern.-

Be it known that I, HERMAN F. STRAW, of Manchester, countyof Hillsborough, State of New Hampshire, have invented an Improvement in Mechanism for Winding Yarns upon Shuttle Bobbins or Quills, of which the following descript-ion, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention, relating to bobbin-winding machines, has for its object the production of a novel organization of mechanism for winding upon shuttle bobbins or quills the chaindyed and beamed filling, as referred to in my application, No. 100,545, for United States patent, filed July 11, 1883, to which reference may be had. In this my improved machine the dyed filling-yarn wound upon a yarn-beam is led, preferably each thread separately, through or between wires, dents, or pins of a raddle, from which latter the said threads are led through the eyes of a. traverse-bar and between feeding-rollers, after which the threads pass over a suitable rest and through eyes of a traverse-rail, and then are wound upon bobbins driven by friction, as will be described, the said feed-rollers being extended lengthwise of the machine. The spindles which rotate the bobbins are provided each with a flange, and each spindle is driven by a whirl loose thereon, the upper flat side of each whirl acting against a friction-washer, preferably of felt, interposed between the said whirl and the flange fixed on the spindle, the adhesion or friction between the flange, washer, and whirl causing the bobbin to rotate and effect the winding of the filling thereon. By driving the bobbin frictionally instead of positively, the filling is always kept taut, and the nose and all parts of the yarn-load are-made of sufficient hardness to avoid tangling when the filling isbeing unwound from the bobbin.

Figure 1 is a plan view of my improved bobbin-winding machine, which one conversant with ordinary spinning machinery may understand; Fig. 2, a section of the same on the dotted line :0 m, Fig. 1; and Fig. 3, an enlarged section taken through the bobbin, footstep, whirl, the sleeve, the washer, and flange of the spindle, the spindle being in elevation.

The beam b, containing the filling a, wound upon it, as described in my other application above referred to,after being dyed,has its 3' our f nals I) placed in suitable bearings, b attached to the stand I), suitably fastened to the floor, and for the best results the said beam 12 has its longitudinal axis in the direction of the length of the machine and of the rows of spindles to be described.

The raddle, supported upon adjustable uprights 0, held by screws 0, is composed of a curved or bow-shaped bar, 0, provided with dents c, or other usual guiding and separating devices for the threads.

The frame-work A of the winding-machine has at its center, and extended longitudinally through the machine, a shaft, B, which is provided with the usual tin or spindle-driving drum, 0, about which are extended the bands (1, which drive the loose whirls e, which surround the spindles s, placed in long rows along the sides of the machine in the direccase serve as an oil-well, and the sleeve of the whirl acts as a bolster for the spindle s. The spindle s has a flange fixed on it, and above the same I have shown a cup, h, into the open top of which the lower end of the bobbin h is inserted, the said bobbin in practice being of any usual shape commonly employed to hold filling-yarn in l-oomshuttles. The bobbin is driven by this cup by friction, but may be driven by a button, or by adhesion to the spindle, as in ordinary spinning-frames.

Between the whirl and the flange h, attached to the spindle, is a felt or other suitable washer, m, capable of exerting such friction that the said flange and the spindle and bobbin wilt derive rotation from friction exerted be tween the whirl and the said washer and flange. The size of the washer may be varied to determine the amount of friction. The whirl will be driven by the band from the drum at the requisite speed. The spindle does not rest at its lower end on the step, but is sup- IC-O portedyertically by the flange resting on the friction-washer only. For the best results the whirl will be rotated at such speed as to rotate the bobbin with little or no slip when the filling is being wound upon that part of the bobbin of smallest diameter; but as the filling is being wound upon a part of the bobbin of greater diameter, or upon the yarn-load of increasing diameter, and the delivery 'of the yarn being at substantially a constant uniform speed, it follows that the bobbin must run more slowly than when the filling is being wound upon the smallest part.

The above arrangement obviates the breakage of filling, which would result if the bobbin were driven always at the same speed. The bobbin is made to drag or fall behind the "speed i of rotation of the whirl, this being practically accomplished by making the whirl '-loose on the spindle, so that the spindle and bobbin may bedriven frictionally by the action of the whirl on the washer and flange.

By the employment of the frictionally-driven 'bobbin the latter may lag behind more and more as the diameter of the yarn-load" is increased; or as the filling is going from one part of the bobbin to another part thereof of greater diameter the latter is made to drag by -the tension of the yarn, which is being delivered at a constant rate, and in this way the drilling may and will always be wound taut upon the bobbin from end to end of the yarn-load, and there will be made what is known as a solid compact nose, or one which will not tangle or break down when unwinding in a shuttle. The tin or spindle-driving drumG is driven by a band upon a pulley, B or in other usual manner, and the shaft B, near the end of the said drum, has a suitable pulley, B, (see Fig. 1,) which by band B and pulley B, or by other suitable connection, drives the feedroller 12, the shaft 10 of which rests in suitable bearings on the stands 16 on the frame A.

The counter-shaft, by which the tin-drum shaft is driven, will in practice contain afast and slow motion device, such as commonly employed on slashers and warpers, by means 'of which the speed of the machine maybe reduced, so as to enable the operator to readily mend threads and clear the rolls of threads which have wound around them, and not stop the machine. f Above the roller 1) is a covered or soft roller, 11, and above it a pressure-roller, 12. Each filling-thread from the beam 1) and raddle c is passed through an ordinary guide-eye, 2, secured to the lower side of the shifting-bar 3, supported by guidearms, and connected by red 4 with the pin of a crank, 5,

on shaft 6, held in bearings 7, the said shaft having fast on it a wornrwheel, 8, engaged at its lower side by a worm, 9, fast to the shaft 10 of the feed-roller 'p. The crank '5 causes the reciprocations of the bar 3, and the attached eyes 2 cause the filling-thread to be moved backward and forward a little between the faces of the rollers 19 and 1l,'so that the cover of the latter will not be worn unevenly. The filling-yarn passed through the eyes 2 is then passed between the rollers 12 and 11, and thence between rollers 11 and p, and the individual threads are turned alternately in different directions, as in Figs. 1, 2-one part over each of the guides 0 at opposite sides of the frame-and from the said guides each of the filling-threads is passed through a suitable eye, a, in a traverse-rail, g, and is attached to the bobbin opposite the said eye, there'being a spindle and eye for each thread orpair or more of threads, if they are to be doubled on the quill.

The traverse-rail g, mounted on suitable lifting-rods, 45, held in suitable bearings attached to the frame-work, will be lifted by the usual builder mechanism common to many spinning-frames-such, for instance, as represented in United States Letters Patent N 0. 186,322, January 16, 1877, wherein the bob bins are wound for filling, and wherein thelifting-rods are marked t, it being understood that the lifting-rods i in the machine herein described may be guided and raised and lowered by mechanism such as shown and described in the said patent, or by-any other usual devices. The speed of the feed-rollers 11 and p, as well as of the drum 0 and whirl, is constant, one depending upon the other; but the speed of the spindle driven by friction, as described, is made variable, being gradually slower as the traverse-rail descends, and vice versa, in order to wind the yarn properly and avoid breaking the same.

In Fig. 1, I have omitted most of the spindles, deeming it necessary to show but a few of them, as they are allalike.

In practice I employ two series of spindles in each side of the frame, one above and alit-' tle back of the other. The axis of the yarnbeam is substantially parallel with or in the direction of the length of the rows of spindles, and the raddle, extended in the same general direction, is elevated above the head of the operator,so that the latter can move about the side of the machine to doff the bobbins or mend broken yarns.

For the successful operation of any machine for winding chain-dyed filling bobbins orquills for loom-spindles, itis necessary, first, that the machine should have a sufficient number of spindles-say from three to four hundredso that the chain as made for dyeing may have a sufficient number of threads to be economically handled in the dyeing and beaming processes; secondly, thatthe various parts of the machine should be so arranged that all parts of the beam, every spindle,and the whole length of each thread from the yarn-beam to the spindle should be readily accessible to the operative for the purpose of mending breakagesandfordoffingthebobbins; thirdly, the parts should be so arranged that if a IIC break down others; fourthly, that the rolls for drawing the yarn fromthe beam and delivering the same to the spindles should be as near as possible to the spindles, so that the threads can be readily kept taut and straight between the yarn-beam and the said feed-rolls by means of friction applied to the yarn-beam, while the tension on the thread after leaving the feedrolls must depend entirely on the frictional spindles; and, further, the yarn, practically in one sheet,between the yarn-beam and feedrolls must be drawn by the latter, that the strain exerted on the sheet will be distributed on all the yarns of the sheet to the advantage of the weaker yarns, while, after leaving the feed-rolls, the threads must be drawn separately downward in opposite directions and wound upon the bobbin by the friction of the spindle, each individual thread being exposed to single strain only for the short distancebetween the feed-rolls and spindles; and, lastly, the spindle and friction for driving the bobbin must be such thatthestrain on the threads can be made practically the same on each of the threads going to the spindles, and that,

too, without causing great trouble to the operative or requiring any delicate adjustment; and this friction must also be such that, with the spindle moving at from two to three thousand turns per minute, the bobbin can fall behind the speed of the whirl at least one-half while the yarn is winding on the largest diameter of the quill, while at the same time the friction must be strong enough and even enough to wind a compact and hard quill in all parts.

I am aware that machines have been devised and described in patents for winding yarn from beams onto spools, but none of them, so far as I am aware, contain the mechanical organization herein described and specifically claimed. I have herein shown and described a spindle driven by friction; but such is not herein separately claimed, as it forms the subject-matter of application No. 140,850, filed August 18, 1884.

I claim- 1. The combination, substantially as shown and described, of the yarn-beam, the curved raddle arranged above the beam. its adjusting devices, the reciprocating eye-bar 3, feed-rollers to draw the thread from the beam under the guidance of the raddle and the reciprocating bar, and the spindles and means to drive them.
